If environmentalists are to protest something, disposable plastic water (and beverage) bottles might be the first thing to boycott. When I was young, they didn't exist and people drank water from drinking fountains (and survived). There were also canteens (reusable metal (later plastic) water bottles.
California declared a war on plastic drinking straws, but compared to plastic bottles, their contribution to the detritus mass that covers the landscape, floats in the ocean and degrades over decades or longer - is NOTHING.
Yet not a peep from the environmental left. Why is that?
Yes, of course, they pick on things that they don't use for boycotts, political action, etc. Hypocritical curs.
Glass breaks, glass degrades, glass sinks, and glass is more easily recyclable.
